AUTOMOBILE JACK AND TURNING DEVICE.

of Illinois, and Whose postbflice address is Post-(lilies Box 1:56,Hinsdale, :l'llinois, have invented certain. new and useful improvementsin Autorhobile'Jaclrs and Turning Devices; and I do herchy declare thatthe following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, and to the numerals ofreference marked thereon, which "form part of this specification.

This invention relates to an apparatus adapted to be associated with anautomobile, particularly trucks, whereby the rear wheels of the truckmay be elevated from the ground as for instance when in a garage, inorder to permit ti'u'ning or shifting of the The apparatus acts not onlyas a jack to support the vehicle, with the rear driving wheels free ofthe ground, hut'is also connected with the power plant to move thevehicle, shitting the same Within a confined area.

My invention involves the use of IDQCili'c nisms of comparatively simpleconstruction readily adapting the device to be associated withpractically any type of motor vehicle, either at the time the vehicle isbuilt, or subsequently thereto. it is an object of this invention toconstr ct an elevating and turning gear for motor vehicles normallycarried in a position out 01 use and adapted to be noted into a positionfor use by'the power of the vehicle, and thereafter operated to turn thevehicle Within a confined area. I

It is also an important object of this invention to construct anautomobile elevating and shifting mechanism at all times as ciated with.the automobile and normally in a position. out of use, adapted to heposi tively moved into operating position by a drive from the powerplant of the automobile and thereafter acting to support and shift theautomobile with the Wheels elevated from the ground in variousdirections, utilizing the power plant of the automobile for the purpose.

It is a further object of this'invention to provide a .motor vehiclewith a supple mentary pair of Wheels journaled transsa 1d tree iyfifl vSpecification of Letters Patent. Application filed March 20, 1915.

The rear wheels aredenoted by the refer-oi numeral 8, and are suitably connected up' therear axle 4c, and the front whe .ed by the reference numeral ug' mountedupon. the front axle 3.

k tly bolted to the side "sills 1 and 2, of the chassis arehearinghraclrets 1 0 and 11, respectively, in which is journaled atransverse shaft 12. Rigidly secured upon shaft 12, is a. ii-shaped leg13, of the U-frame.

sion 6, and differential 7, is denoted by the reference numeral 17, andat a point intermediate its ends is provided with. a helical gear 18,which, for certain positions of the U-frame 13-14, meshes with thehelical gear 16. At one end of said shaft 16, a

bevel pinion 19,- is secured which meshes with a bevel pinion 20,secured on the upper end of a shaft 21, which is iournaled on the IThelower end of said shaft 21, is provided with a bevel pinion 22, whichmeshes with a bevel pinion 28, which is in turn rigidly connected to aroller or supporting wheel 24, journaled at the lower end of the leg 13.Another similar roller or wheel 25, is journaled at the lower end of theleg 14, although in the latter case no driving connections therefor areprovided. When the aforesaid transverse shaft 12, is rotated the U-frameand the I mechanisms associated therewith is moved into variouspositions, one extreme position of which is shown in dotted lines inFig. 4, and the other extreme position or that in which the device is inposition for use, being i shown in full lines insaid figure. For thepurpose of rotating said transverseshaft 12, and thus manipulating theU-frame into the desired position, a pinion-26, is secured upon saidshaft and meshes with a slida-ble rack 7 27, mounted along the chassissill member 1,

and movable through brackets 28, provided therefor. A powerdrivenmechanisrn is provided for actua tting therack 27, and for thispurpose a ch] ch member 29, -is feath ered upon the forward end of thecrank shaft of the engine and is adapted to be thrown into interlockingengagement with a clutch-worm 30, rotatable on the crank shaft, withacoiled spring 31, disposed between said clutch vmembers acting normallyto.

for said clutch member 29, is pivoted on an extension; 41, at theforward end-of the engine, and 'at one end is provided with a tooth'42,adapted to engage in thenotches s of the U-fram'e."

Such movement 'ofthe clutch lever 40, causes a the tooth42,- to be withdrawn=from the notch 36, in the disk 35, which, ofcourse, 8 begins to rotate, and the clutch-lever 40, is 1 thus held bycontact with said tooth'42, on-

As the chassis moves rearwardly, the rollers 24 and 25, however,maintaining a fixed position, the

rear wheels 8, finally are lowered'into con-,

1 am aware that various details of construction may be varied through awide range without departing from the principles of this invention, andI therefore do not purpose limiting the patent granted otherwise thannecessitated by the prior art.

I claim as my invention:

1. In a device of the class described, the combination with anautomobile, of a supplementary frame connected thereto and adapted .tobe adjusted to support the automobile with the drive wheels out ofcontact with the ground, connections with the engine of the automobilefor operating said frame, and rollers mounted on said frame and drivenfrom the main drive shaft of the automobile when clutched to theautomobile drive wheels. i

2. In a device of the class described, the combination with anautomobile, of supplementary wheels for supporting the same with thedriving wheels of the z tomobile out of contact with the ground, "aadjust- ,able frame on which said supplementary wheels are mounted, andconnections for.

said supplementary wheels and frame whereby said frame may be adjustedby the said supplementary Wheeis driven from the main drive shaft of theautomobile when clutched to the automobile drive wheels. 7

3. In a device of the class described, the combination with anautomobile, of an adjustable wheel carrying frame mounted near one endthereof, a foot treadle, means operated. by said treadle forcommunicating the engine DOWeI to said frame to move its wheels intocontact with the ground to elevate that end of the automobile, saidmeans automatically disconnecting from the engine power upon thecompletionv of said movement, and said means adapted, upon a furtherdepression of said treadle, to return said frame to its initialposition. 7

l. In a device of the class described, the combination with anautomobile, of an adjustable wheel carrying. frame pivotally mountednear one end thereof, a pinion on said pivot connected with said frame,a rack in mesh with said pinion, a foot treadle, means operated by saidtreadle for communic'ating the engine power to said rack, whereby saidframe will be rotated through said pinion to a position with its wheelsin contact with the ground to elevate that end of the automobile, meansautomatically dis connecting said engine power from said ,rack upon thecompletion of said movement,

and said intermediate driving means adapted, upon a further depressionof said treadle, to operate said rack to return said frame to itsinitial position.

5. In a device of the class described, the combination with anautomobile, of an adjustable wheel carrying frame pivotally mounted nearone end thereof, a pinion on said pivot connected with said frame, arack in mesh with said pinion, a foot treadle, a disk to which said rackis eccentrically connected, a clutch operated by said foot treadle forconnecting said disk with the, engine drive shaft, whereby a halfrotation bf said disk will operatesaid rack to rotate said frame to moveits wheels into contact with the ground to elevate that end of theautomobile, and means automatically disconnecting the engine power fromsaid disk upon the completion of said movement, said disk when againconnected with the engine power through another depression of saidtreadle, upon a further half rotation, returning said rack to itsinitial position and thereby also returning said frame to its inactiveposition.

In testimony whereof I have hereunto subscribed by name in the presenceof two subscribing witnesses.
